摘　　要：网络控制系统的故障检测是一个新的研究课题。充分考虑了网络控制系统的延时特性,并基于观测器的方法来分析网络控制系统的特性。只考虑从传感器到控制器的网络时延,构造一个具有时延补偿功能的最优观测器来估计系统的全部状态,最后得出系统的残差只跟故障和噪声有关的结论。The fault detection of NCS is a new research topic.The paper considers NCS time-delay and analyzes the characteristics of NCS based on the observer method.Only considering the time-delay between the sensor and the controller,an optimal estimator with time-delay compensation function is constructed to estimate the whole state of the system,at last the conclusion that the system residual signal is only related to fault and noise is obtained.

关 键 词：网络控制系统 故障检测 卡尔曼滤波器
